On the Use of Local Ray Termination for Efficiently Constructing Qualitative BSPs, BIHs and (S)BVHs KU Leuven
Acceleration data structures (ADSs) exploit spatial coherence by distributing a scene’s geometric primitives into spatial groups, effectively reducing the cost of ray tracing queries. The most effective ADSs are hierarchical, adaptive tree structures such as BSPs, BIHs and (S)BVHs. The de facto standard cost metric for building these structures is the Surface Area Heuristic (SAH), which assumes a scene-exterior isotropic ray distribution of ...
